Winner: Mariano Rivera

Mariano Rivera continues to defy odds and make his stamp as one of the greatest players to ever step on the field.

Coming off a torn ACL and heavily considering retirement over the offseason, Rivera decided to come back for his swan song.

In 2013, Rivera has simply been perfect and looks better than ever at age 43. Rivera has converted all 16 of his save opportunities this season with an ERA of only 1.56 and batters hitting .219 against him.

Yankees fans are going to be in for quite the shock once Mo hangs them up at seasons end. How will they ever replace somebody who is one of a kind?

Loser: Phil Hughes

Someone in the Yankee system should remind Phil Hughes that he is pitching for his next contract.

The soon-to-be free agent has had a roller-coaster start to the season with what seems to have had more lows than highs, as the 26-year-old is 2-3 with a 5.88 ERA.

There were high hopes for Hughes coming into this season as a potential breakout year, but that has not come to fruition. If he slumps his way through the entire season, it surely will be his last in a Yankees uniform.

If the Yankees can't get the most out of their young pitcher in a contract year, there is no real hope going forward for the right-hander.
